A rigid bar in the shape of a T has a mass of 10 kg. The T-shaped body of mass m is composed of two identical slender bars welded together. End A is constrained to move in the slotted frictionless groove guided by the light frictionless roller as shown in Figure 3. The lower end of the T is released from rest in the vertical plane in the position shown, and the dimension /= 1 m. (i) Determine the location...

A uniform slender bar AB of mass m has two light pegs A and B
which are constrained to move in the frictionless circular slot
with center O in the vertical plane. At the position depicted, the
bar is released from rest. Find the bar's initial angular
acceleration when the bar is released in terms of appropriate given
quantities. The pegs each contact only one side of the slot at a
given time.

PROBLEM 17.113 The slender rod AB of length L = 1 m forms an angle B = 30° with the vertical as it strikes the frictionless surface shown with a vertical velocity 7 = 2 m/s and no angular velocity. Knowing that the coefficient of restitution between the rod and the ground is e = 0.8, determine the angular velocity of the rod immediately after the impact.
